	Description:		H. JAY MELOSH: What killed the dinosaurs? And is humanity headed for a similar fate? These questions are addressed by H. Jay Melosh, a Professor of Theoretical Geophysics at the University of Arizona, in this lecture entitled, "Death of the Dinos: Giant Impacts and Biological Crises".
